construct a device of this character in such a manner that a maximumvolume of sound may be had. I

It is a further object of the invention to construct the device in sucha manner that the stylus or needle may be ositioned at various anglesrelative to the entiphone.

With the above and other objects in view, reference is had to theaccompanying drawin s, in which igure 1 is a view in elevation of oneform of dentiphone constructed in accordance with the present invention;

Fig. 2 is a similar view thereof taken at ri ht angles to Fig. 1;

ig. 3 is a detail view of a modified form of the invention, in which thedevice comprises two sections detachably secured together;

Fig. 4 is a view of the two sections of the device in disassembledrelation;

Fig. 5 is a detail sectional view showing the manner in which the twosections of the dentiphone are detachably secured together;

Fig. 6 is a detail sectional view of the head of the dentiphone showingthe manner of mounting the stylus or needle therein;

Fig. 7 is a detail view partly in section showing the mouth end or headof the dentiphone;

Fig. 8 is a detail sectional view showing a slightly modified form ofhead and stylus holder.

Referrin more particularly to the draw-.

the reception of a stylus. The portion intermediate this stylus head andthe central portion 10 is relatively thin as designated by the referencenumeral 15, and as more clearly shown in Fig. 2, that portion of thedentiphone between the body 10 and the mouth end 12 is relatively thinas designated by the reference numeral 16, and as shown in Figs. 1 and 2these portions 15 and 16 are relatively thin in planes at right anglesto each other. The mouth end 12 is provided with a removable cap, or thelike,

17, which removable cap is formed of fiber, paper, or similar material,and is used for sanitary reasons.

In using this form of the invention, a stylus is placed in one of theseveral openings 14, the opening employed being determined by theposition of the person using the device relative to the talking machine.After the stylus has been positioned, it is engaged with the record, itbeing understood that the opposite end of the device is placed betweenthe teeth of the operator. If, now, the talking machine be started, thetravel of the stylus through the sound groove of the record will causethe vibration set up bythe record to be transmitted through the body ofthe dentiphone and through the teeth of the user, and will thus transmitall of the tones and sounds to the user in a clearly understandablemanner.

In that form of the invention shown in Figs. 3 to 5 inclusive, thedevice comprises two members 20 and 21. Each of these members has a mainbody portion which is substantially rectangular in cross sectional form,and such members have relatively thin flattened portions 22 and 23,respectively. The member 20 is provided with a stylus or needle head 24,and the member 21 is provided with a month end 25 having a protectingcap 26, as in the heretofore described form of the invention. As shownin the drawings, the member 21 is bifurcated as at '27, and the member20 has a tenon 28 adapted to be received within the furcations of thebifurcated member 21. A bolt passes through the furcations of thebifurcated member 21 and through the tenon 28 of the member 20, the boltbeing designated by the reference numeral 29. This bolt carries a wingnut 30, or the like, by means of which the furcations may be placedunder tension to trictionally engage the tenon 28 to permit ofiltljllritllitnt or the members 20 relativelj-J thin portions and 2 5 atright angles to each other so that they occupy positions similar to thatin the previously described form of the invention, that is, at rightangles to each other.

in l S shown a slightiy modified form or stylus read 10, and in thisfigure the elercn e numeral it) dos ites a plurality of s eivine'openings 4:1, 1" permits 0 nine" of a stylus at various angles it )honcin such a manner that th stylus m be used upon either side of the head.and either to the right or left 01' the central point of the ree- 0rd ortable upon which it mounted.

Erom the foregoing it is aoparent that the present invention provides adevice which will permit persons deal or non-deaf L li construction toenjoy the pleasure afforded by the use of phonographs and the like.

It is also apparent from the above that all of the objects of thepresent invention have been accomplishet, and, further, it should beunderstood that numerous IUOili lications of structure might readily beresorted to Without in the hast departing from the scope of the claims.

hat is claimed. is

l. A device of the character described comprising a plurality ofresilient members, means for adjustably securing said resilient memberstogether, a stylus head carried by one of said members, and a mouthpiece carried by the other of said memljiers.

A device of the character described comprising a plurality of resilientmembers :uljustably secured together, said members being disposed inplanes at right angles to each other.

3. A device of the character described comprising a plurality ofresilient members means for pivotally securing said members together, astylus-carrying head formed on one of said members and a mouth piececarried by the other of said members, said mouth piece being positionedin a plane at irigxhlt angles to that of the stylus-carrying ieac.
